The German brothers – Sven a graphic designer and Nils a machine artist (see our previous post) – collaborated by combining four walls with 304 framed graphic pages surrounding a field of 252 inflatable silver cushion-like air bags. The bags were programmed by Nils Völker to create sequences according to chapters of his brother’s “books on wall”. The inflating and deflating of the bags, along with the colored lighting system, create a very dramatic and intensified effect.
